How can you prepare para-nitro acetanilide from acetanilide?
used of para nitro acet anilide
Why in bromination of acetanilide using bromine in acetic acid give para bromoacetanilide as major product?
The -NHCOR group is less powerfully activating then the -NH2 group. In addition, the degree of steric hindrance is much greater in the case of a -NHCOR group, such as is found in acetanilide. This results in the compound being much more para directing. For an example, see Morrison and Boyd 's text "Organic Chemistry", sixth edition, Page 848.
What is melting point of para bromo acetanilide?
166-170 ºC
What are the examples of Ortho and para directing group and mata directing group?
Electrophilic Aromatic Substitution is an example of Ortho and para directing group and meta directing group.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
Why acetanilide brominates in the ortho and para positions and the amount of o-bromoacetanilide?
The polarization of bromine in bromoacetanilide reaction
Salicylic acid is ortho para directing group or meta directing group?
salicytic acid is a ortho para directing group ....however check up on that ...i am not completely certain .. Actually, it is a meta-directing group, because of the carboxylic acid functional that the salicylic acid contains. Hope that was helpful.
What is the function of acetic acid in the preparation of para nitro acetanilide?
it holds the carbocation that is formed in "soultion" so it is able to react to completion
Why para-nitro acetanilide is insoluble in water whereas ortho-nitro acetanilide is soluble in water?
p-nitro phenol has a symmetric structure as compare to o-nitro phenol so it has higher dipole moment or polarity so is more soluble.
Why is only 4-bromoacetanilide created mainly from a bromination of acetanilide?
The Acetanilide is a benzene with a acetamido group attached to it. The acetamido group is electron donating and therefore it directs other substituents to the ortho and para positions. The acetamido group is also a very large group and the ortho position is right besides the acetamido group. This creates steric hindrance from bromine from getting to the ortho position and therefore only para-bromoacetanilide or 4-bromoacetanilide is created mainly from a bromination of acetanilide.
Why 4-hydroxybenzoic acid is less acidic than 2-hydroxybenzoic acid?
4 hydroxybenzoic acid is para directing group whereas 2 is ortho directing group. thus at para, the two groups i.e. alcohol and carboxyl are far apart and thus dont show steric hinderance. therefore para directing group is a stable and as a result less acidic.
Why can't acetanilide dissolve in HCl?
Why is not acetanilide soluble in HCL?
